Specification of Letters Patent.

Patented Apr. 1,4, 1914.

Application Ied December 1, 1913. Serial No. 803,928.

To all whom t may concern Be it known that I, JOSEPH PATRICK, a citizenof the United States of America, residing at Crabtree, in the county ofWestmoreland and State of Pennsylvania, have invented certain new anduseful Improvements in Couplers, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to couplers for mine, pit and other types ofcars, and the primary object of-my invention is to provide a car couplerof novel construction that permits of cars being easily and quicklyuncoupled without the necessity of miner or trainman getting between thecars to uncouple the same.

Another object of this invention is to provide a car coupler having anovel link releasing device that under ordinary conditions holds a linkas a coupling means between two cars, yet permitting of the cars beingquickly released, particularly as the same are fed onto a tipple.

A further object of this invention is to provide a car couplerconsisting of comparatively few parts that are inexpensive tomanufacture, durable and applicable to the present type of pit cars.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a plan ofthe coupler, Fig, 2 is a longitudinal sectional view of the same, andFig. 3 is a cross sectional view of the coupler.

In the drawing, the reference characters A and B denote portions of pitcars and the reference numerals 1 and 2 the sills of the cars A and Brespectively. The cars are provided with longitudinal draw bars 3 and 4,the draw bar 3 having a loop 5 at one end thereof and the draw bar 4 apin 6. Movably mounted in the loop 5 is an oblong link 7 having a crossbar 8 connected to one end of a coiled retractile spring 9, the oppositeend of said spring being connected to an eye bolt 10, carried by the endwall 11 of the car A. The link 7 is adapted to swing downwardly over thepin 6, as shown in Figs. 2 and 3. Mounted upon the sill 2 ofthe car B 1sa bearing plate 12 provided with straps 13 and movable in said straps isa slide bar 14 having a longitudinal slot 15. Extending upwardly throughthe slot is a pin 16 for limiting the movement of the slide bar 14 uponthe bearing plate 12. The pin 16 is provided with a nut 17 coperatingwith the straps 13 in preventing the bar 14 from becoming accidentallydisplaced. The inner end of the bar 14 is bifurcated, as at 18 toprovide clearance for the pin 6 and at the same time extend over thelink 7. The outer end of the slide bar 14 is twisted and pivotallyconnected, as at 19 to the slotted portion 20 of an operating lever 21.The lower end of the operating lever is pivotally connected, as at 22 toa bracket 23 carried by the side of the car B. The upper end of thelever is adapted to be engaged by a pivoted link or hold-fast device 24.By releasing the lever 21 and pulling outwardly upon the same the slidebar 14 is shifted from above the link 7, and the tension of the spring 9is sufficient, under ordinary circumstances, to elevate the link andthereby uncouple the cars. The link 7, when in an elevated position, canbe easily lowered over the pin 6 and the cars coupled without any dangerof the fingers being caught between the sills of the cars,

The coupler in its entirety can be made of light and durable metal andused in connection with various types of vehicles.

One embodiment of the invention has been illustrated, but it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaim.

What IV claim is In a car coupler, the combination with car sills havingdraw bars, of a link loosely In testimony whereof I aHiX my signatureconnected to one of said draw bars, a coiled 1n the presence of tWoWitnesses.

retractil@ spring connected to said link, a pin carried by the other ofsaid draw bars und over which said link is adapted to eX- tend, and abifurcated slide b21-r adjacent to said pin and adapted to extend oversaid link to hold said link in engagement with said pin.
